Question

基本上，我有一个游戏，要求我调用扩展skpritenode类的对象中包含的两个方法。我想使用touches begin方法检测节点触摸，从该节点中拉出对对象的引用，然后将该引用分配给touchesBegan方法内部的一个临时变量，该变量可以让我调用其方法。抱歉，如果不清楚，我仍在尝试习惯于“正确”的方式来提出我的问题。

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch = touches.first
    if(atPoint((touch?.location(in: self))!) == homeButton) && scene?.isPaused == false{
        goToHomeG()
    }

    else {
        if let location = touch?.location(in: self){
            let theNodes = nodes(at: location)
            for node in  theNodes{
                if node.name == "yesText" {
                    let transition = SKTransition.flipHorizontal(withDuration: 0.5)
                    let menuSceneOB = MenuScene(fileNamed: "MenuScene")
                    menuSceneOB?.scaleMode = .aspectFill
                    self.view?.presentScene(menuSceneOB!, transition: transition)
                    node.removeFromParent()
                }
                else if node.name == "noText" {
                    for child in self.children {
                        if child.name == "goToHomeText"{
                            child.removeFromParent()
                        }
                        if child.name == "noText"{
                            child.removeFromParent()
                        }
                        if child.name == "yesText"{
                            child.removeFromParent()
                        }
                        if child.name == "box"{
                            child.removeFromParent()
                        }
                    }
                    scene?.isPaused = false
                }
                else if node.name == "enemy"{
                    //here is where I want to detect if the object is an enemy and then use the assignment to the location to modify the object with its own internal methods.
                    var modify : EnemyChar?
                    modify = node
                    modify.update
                }
            }
        }
    }

}

如果我理解正确，则只需要投射CREATE EXTERNAL TABLE `machine_data`(`ids` string,`delta` string,`locatio` string,`time_data` string,`valid` boolean,`measure` string,`val` float ) PARTITIONED BY (`nodename` string) CLUSTERED BY (delta) INTO 53 BUCKETS ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.orc.OrcSerde' STORED AS INPUTFORMAT 'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat' ;：

node

顺便说一下，这段代码：

else if node.name == "enemy"{
    //here is where I want to detect if the object is an enemy and then use the assignment to the location to modify the object with its own internal methods.
    var enemy = node as? EnemyChar
    enemy.update()
}

可以简化为：

for child in self.children {
    if child.name == "goToHomeText"{
        child.removeFromParent()
    }
    if child.name == "noText"{
        child.removeFromParent()
    }
    if child.name == "yesText"{
        child.removeFromParent()
    }
    if child.name == "box"{
        child.removeFromParent()
    }
}

使用touchesBegan方法从节点获取对对象的引用
